LAMP ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 793,496, dated June 27, 1905. Application filed September 28, 1904:. Serial No. 226,356.

lb all whom it may concern: 7

Be it known that I, SIDNEY ANKEL, acitizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Lamp Attachment, of which the following is a speciiication.

This invention relates to an improvement in lamps, and has for its object to provide an attachment by which the lamp chimney and globe may be independently raised, as is often desired for obvious reasonsfor instance, lighting the lamp, trimming the wick, inspecting the light, and for other purposes that often ariseand thus avoiding the necessity of entirely removing the globe and chimney when it is desired to light the lamp or inspect the wick after it has been lighted.

W'ith these briefly-stated objects in view my invention comprises certain details of construction and novelties of combination and arrangementof parts, as will be fully described in the following specification and pointed out in the claims, reference being had to the drawings, in which- Figure 1 is an elevation of a lamp embodying my improvement. Fig. 2 is an enlarged detail sectional elevation of the same. Figs. 3 and 4 are details of construction.

In practice I desire it understood that my improvement may be applied to the ordinary construction of wick-lamps, and no material change is necessary in the construction of the lamp other than making the globe and shade supporting disks detachable, and in applying my invention to a lamp I employ two tubes A and B, which are preferably closed at their lower ends, said tubes being soldered or otherwise connected to the body portion or well of the lamp with their lower closed ends extending down into the well, as clearly indicated in Fig. 2 of the drawings. Operating in these tubes A and B are the tooth-bars C and I), respectively, the bar C having its upper end connected to and terminating in a ring C, which encircles and is firmly clamped to a flange of the chimney-supporting disk or holder and operating in the tube B is a tooth-bar D, similar in construction to the bar C and also having its upper end connected to or terminating in a ring D, which is clamped to a flange D of the globe-supporting disk D.

Each tube C and D carries a pair of cars E, in each pair of which is journaled a short shaft F, carrying a gear F, which is positioned between the ears to mesh with its respective toothbar, and these shafts are operated by a thumbwheel- F carried at the outer end of each shaft.

From the foregoingit will be seen that when the shafts are operated the tooth-bars through the'medium of the gears will be elevated and carry the concentrically-arranged globe and chimney supporting disks, and the said chimney and globe will likewise be elevated to permit access to the Wick-tube of the lamp, and in order to hold the parts in such position I employ pawls Gr, which are pivotally arranged upon the shafts in such position that they may be readily thrown into engagement with the tooth-bars, and it will of course be understood that when it is desired to lower the chimney or globe the pawls maybe readily disengaged from the bars and the latter lowered to their proper positions. It will also be understood that should it be desired to elevate only the globe, which is often desired for the purpose of inspecting the light, the bar supporting the globe-disk may be operated without afl ecting the position of the bar which supports the chimney.

In Fig. 2 of the drawings I have illustrated the bars and their coacting parts upon each side of the perforated sleeve which surrounds the wick-tube; but this is done solely for the purpose of illustration, as they will in practice be arranged side by side, as shown in Fig. 1 of the drawings However, I do not Wish to limit myself to the exact position of these parts, as they may be arranged in various places upon the lamp and, if desired, may be arranged entirely within the perforated sleeve which surrounds the wick-tube, with only the operating-wheel projecting outside of the said sleeve. I also desire it understood that slight modifications may be made in my invention without departing from the broad scope or principle of the same.

Having thus fully described my invention, What I claim as new, and desire to secure by Letters Patent, is

1. In adevice of the kind described, the combination with a lamp, of concentrically-arranged chimney and globe supporting disks, and means for simultaneously or separately elevating the said disks.

2. The combination With a lamp having separately-movable chimney and globe supporting disks, of a bar supporting each disk, and means for separately elevating each bar.

3. The combination With a lamp having concentrically-arranged chimney and globe supporting disks, the latter being adapted to move 5 vertically on the former, of tubes carried by the lamp, toothed bars operating in the tubes, a ring carried by each bar and connected to one of the disks, a shaft journaled in each tube,

gear-Wheels carried by the shafts meshing 26 with the toothed bars, and a curved pawl carried by each shaft and adapted to engage the adjacent toothed bar.
